How to take a full screenshot while using google chrome?

While browsing in google chrome press F11 for full screen & press print screen key & paste and save in paint

To take full screen shot, as suggested by the other person "Print Screen" is a tuf job. Try 'Snag it' Software. It Rocks.

Not just in Google Chrome, but in ANYTHING, pressing the Print Screen button (on the upper right of a standard keyboard, if you're using a laptop look in that region. On a standard keyboard look straight up from the left arrow key, it might say PrtScr or something) will capture everything, and I think Alt-PrintScreen (if not, then Ctrl-PrintScreen) will only get the current window - without the Start Bar, etc. This captures it to the Windows Clipboard. Then you have to use some picture program - Windows Paint if you have nothing else - to Paste it, then you can do what you wish: Crop, Edit, Save, whatever.

You can use the "print screen" key in the keyboard while using Google chrome in Full screen mode so that you can get the image in full clarity. And you can crop the regions as per your needs.
